CHARLES SCHLEICHER, OF LOUISVILLE, KENTUCKY.

IMPROVEMENT IN LATH-MACHINES.

Specification forming part of Letters Patent No. 111,259, dated January 24, 1871.

To @ZZ whom t may concern:

Be it known that I, GHARLEs ScHLEIcHER, of Louisville, Jefferson county, Kentucky, have invented a new and useful Lath-Machine and I do hereby declare the following to be a full, clear, and eXact description thereof, reference being had to the accompanying drawings, making part of this specification.

My invention relates to a machine for the manufacture of laths out of suitably-prepared slabs; and it consists `in the construction, arrangement, and combination of parts, as hereinafter fully described and claimed.

Figure l is a perspective view of a machine embodying my invention. vation thereof.

A is an open rectangular frame having journaled horizontally within it a shaft, B, furnished at one end with a gang of circularsaws, C, secured at equal distances from each other, corresponding with the thicknesses of the laths to be cut. The shaft B is driven at a high speed by means of suitable belted connection, D D', with pulleys E E' E" E on the said shaft B 'and on the counter and driving shafts F and G.

H is a pedestal secured to the side of the frame A,-and capable of vertical adjustment by means of a tail-screw, I.

Journaled horizontally in the pedestal H is a shaft, J, having a pulley, K, belted, L, to a smaller pulley, K', on the drive-shaft, and having a pinion, M, which drives a spurwheel, N', on another horizontal shaft, O, in the pedestal H.

Hinged to one end of the frame A is a bed or table, P, traversed by as many slots Q as there are saws. The free end of the bed P rests upon a set-screw, Z, by which it is supported at the proper elevation.

Journaled horizontally in the bed P is a shaft, R, having a gang of disks, S, capable of rotating either with or around said shaft, each disk in the plane of one of the saws C.

'I is a gage or shoulder, against whose vertical surface the stuff is pressed as it is fed forward to the saws.

U U' are two feed-rollers, of which the upper one, U, is the driver, its shaft V having a spur-wheel, W, which gears to the wheel N'. The shaft V is held down at its forward end Fig. 2 is a side eleby a spring, X, adjustable in its tension by the screw m, while the rear end of the said shaft rests upon a spring, Y, adjustable in its tension by means of a screw, y. Match-wheels W W', near the rear ends of the shafts of the respective feed-rollers, enable the driving of the lower one by the upper one.

It will be seen that the described arrangement of the gang of circular saws C and hinged and slotted bed P Q enables the instantaneous clearing of the saws of any chips or other trash with which they may become choked or clogged. The said hinged arrangement also enables the said bed to be lifted for examination, adjustment, or replacement of the belts, orlubrication ofthe journals. The said hinged arrangement, also in connection with the setscrew Z, enables the elevation or depression of the upper surface of the said bed with respect to the saws, for the most advantageous cutting agreeable to the width of the laths and other circumstances. Y

It will beV perceived that the upper feedroller, U, is capable of yielding upward, and

-the rear end of its shaft of yielding corre-V spondingly downward, so as to enable a steady pressure, even upon rough or irregular "maa terial.4

I claim herein as new and of my inven`- tion-- 1. The upper feed-roll, U, and its shaft V, v

arranged with the adjustable springs X Y, in the manner described and shown, for the purpose specied.

2. The gang of disks S on the shaft R, in combination with the adjustable gage 'I and gang of saws C, all as herein set forth.

3. The arrangement of the slotted bed P,

hinged at one end to the frame A, the screw Z, gang of saws C, gang of disks S, gage T, fixed and yielding feed-rolls U and U', and the adjustable. springs X Y, all constructed and operating substantially as herein :shown and described.

In testimony or" which iiivcntion I hereunto set my hand. l

CHARLES SCHLE-ICHER.
